Application June 20, 1935, Serial No. 27,609. In Switzerland June 23, 1934 15 Claims. (Ci. 8-20) 'It is known that when tertiary amines are treated with suitable oxidizing agents they may be converted into so-cal1ed tertiary amine-oxides.

Hitherto these products have only been described in scientific literature and there has been no 5 reason to suppose that they could be applied as assistants in the textile industry.

It has now been found that certain of these tertiary amine-oxides, i. e. those which, due to their molar magnitude, are not soluble in mercerizing baths, or only sparingly soluble, but which can be dissolved in mercerizing baths with aid of so-called solubility-promoting agents, may be used for the production of excellent wetting agents for mercerizing liquors. In order to produce such wetting agents for mercerizing baths,

it is only necessary to mix these amine oxides with, the so-called solubility-promoting agents.

To the compositions of matter thus obtained there may be added further substances, such as, for example ether alcohols, for instance, glycolmonobutylether, glycerine-monoalkylether and glycerine-dialkylether.

As amine-oxides which come into consideration for carrying out the present invention there may i be named amine-oxides derived from tertiary amines which contain at least one radical comprising 3 carbon atoms, such as, for example, the propyldimethylamine-oxide oi the formula- CHPGHPCHPI1I=O the propyldiethylamine-oxide of the formula- CHI YOHr-CHz-OHr-N=O I 13' 40 the butyldimethylamine-oxide oi the formula- CH: CH:-'CHr-CHr-CHr-I T=O I (3B4 the dipropylmethylamine-oxide of the formula-- CHr-CHr-CH:

, OHr-CHr-CHg-N=O 1 HI the butyldiethylamine-oxide of the formula- CHrCHr-CH:CH:N- O

the li-butylpiperidine -oxide oi the formula- CHr-C cnroar-cnrcnrn OKs-CH,

the dimethylcyclohexylamine-oxide of the formu- 1a W V CH:

CIiCH: CH1

the diethylcyclohexylamine-oxide of the formu- 1a- CHr-OHi CHz I 10 the methylhydroxyethylcyclohexylamine-oxide of CHP-CHI III Hr-CHr-OH 20 the phenyldimethylamine-oxide of the formulathe benzylpiperidine-oxide of the formula QHr-CH:

CHz-CH: 30

etc. All these compounds are oxides derived from such tertiary amines which contain not more than 12 carbon atoms and which contain at least one radical which comprises at least 3 carbon atoms. Of these amine-oxides, those are particu- 35 larly valuable which are derived from non-aromatic tertiary amines; further those non-aromatic tertiary amines which contain at least one radical comprising 4 to 6 carbon atoms, But if use is made of amine-oxides which are derived 40 from tertiary amines'containing higher aliphatic radicals, such as, for example, the dodecyldimethylamine oxide, no compositions of matter are obtained which are useful as wetting agents, for mercerizing baths, since the solubility-promot- 45 ing agent is no longer capable of keeping such highly molecular amine-oxides in solution in mercerizing baths. The low molecular amineoxides, such as trimethylamine-oxide or triethylamine-oxide are useless, since as such they are too easily soluble in the mercerizing baths.

Solubility-promoting agents. 1. e. products which have been selected from a group of com-'- pounds consisting of phenols, or highly suli'onated 55 oils. and which have the property of increasing the solubility of organic compounds in mercerizing baths, are for example, phenol itself, the various cresols, crude cresol, phenols substituted in the aromatic nucleus by alkyl radicals commercerization.

prising more than one carbon atom such as the alkylor propyl-phenols, highly sulionated castor oil and the like. The following examples illustrate the invention, the parts being by weight:-

Example 1 25 parts of butyldimethylamine-oxide are mixed with 75 parts of crude cresol. The mixture may be used forthwith as an assistant in tained, if instead of '75 parts of crude cresol a mixture of 65 parts of crude cresol, and 10 parts of glacial acetic acid is used.

Example 2 To a memorization liquor '"(sodium hydroxide solution of 30 B.) there is added, per litre,

Li uor Liquor Seconds wit out with I addition addition The liquor to which the addition has been made remains quite clear even on long standing and after 72 hours has the same shrinkage values as those recorded with the liquor immediately after addition has been made.

Example 3 To the mercerizing liquor there is added, per litre, 5 grams of a mixture consisting of 38.5 parts of dimethylaniline-oxide and 61.5 parts of crude cresol. solved in the mercerizing liquor. The tests made in the same manner as described in Example 2 'gave the following shrinkage values:-

- Li 1101' Liquor Seconds wit out wit addition addition A like mixture, which contains dimethylaniline instead of dimethylaniline-oxide is completely useless on account of the immediate separation of the base.

For the foregoing amine-oxides there may be substituted n-butyl-piperidine-oxide, benzylpiperidine oxide, dimethyl-cyclo-hexylamine-oxide, diethylcyclohexyiamine oxide, methyloxyethylcyclohexylamine-oxide or these, or the like.-
